2 Claims. (01. 25-1-9) This invention relates to a novel airconditioning plant which is especially, but not necessarily, adapted fordomestic usage and which is constructed to. performasan air coolingsystem in ing system during the winter or colder months.

My primary aim is to provide a single structure for performing bothoperations, which structure is capable of installation in the ordinaryhome I [Q and constructed to accommodate a suitable charmatic typeshowing the manner in which the complete operative system is installedin the cellar and associated with superposed rooms.

Figure 2 is a viewin section and elevation illustrating the principalfeatures of construction as designed in accordance with the presentinvention.

Figure 3 is a top plan view of theair intake and preparing device orunit.

Figure 4 is a central vertical sectional view through said unit.

Figure 5 is a view similar to Figure 2, the section being at approximateright angles to Figure 2 to show the internal association of parts moreplainly.

35 Figure 6 is a plan view of a supporting spider for the fan motor.

Attention is first invited to Figure lfwherein it will be observed thatthe air trapping and distributing casing or enclosure is distinguishedbyv the numeral 7. This is of appropriate proportions, material andshape. It may resemble an ordinary cellar furnace. In fact, it doesresemble such a furnace in that it includes a hinged door 8 to permiteither the heating or cooling 5 medium to be inserted, and it isprovided at its bottom with a refuse removal door 9, by way ofwhichashes and used ice water may be disposed of. Then too, at the top Iprovide outlet collars 10 through which the conditioned air passes'intoconveying pipes or the like 11 where it is conveyed into the upper roomsand discharged by way of an appropriate register or the like 12 into thesummer and warm weather and as an air heatcasing where it enters thecasing as shown in Figures 1 and 2,

Referring now to Figure 2, I call attention to the central horizontalpartitioning plate 15 which divides the easing into upper and lowerchambers 16 and 17 respectively. The chamber 17 serves to accommodatethe air intake pipe 14 and the associated air preparing device or unit18. This is supported or hung in the chamber 17 from the partitioningplate 15 as illustrated in the drawings. Moreover, as shown in Figure 4,this particular device embodies a conical receptacle '19 formed with anintegral cylindrical cup-like fan housing 20.

In the fan-housing is a spider ring 21 and attaching arms 22 for saidring, the ring serving to support a conventional electric motor 23, fordriving the rotary fan 24. The fan sucks air in through the inletnipples 25 from the pipes 14 where it is pre-treated before entering thechamber 16. In the first place, the air comes into contact with anelectric refrigerating coil 26 of appropriate construction. Then it isdrawn up by the fan and the air currents project against the conicalhood 27. This hood is attached in spaced relation by brackets 28 to theupper end of the cylindrical housing 20 whereby to provide for dischargeof the air and the hood is of appropriate diameter as to overhang thehousing in the manner shown. The hood serves essentially as as a shieldand water spreader. In fact, a water delivery pipe 29 serves to dropwater onto this shield so that the incoming air is passed through thefilm of water and washed and moistened and then driven under pressure byway of the fan 24 into the final conditioning chamber 16. It will benoticed in this connection that the numeral 30 designates a drainport'and 31 a similar drain port to which pipes 30a and 31a connect inorder to carry the used water to an appropriate point of disposal.Incidently, this air washing and moistening means are used when theplant is employed for either heating or cooling purposes. Manifestly,however the cooling unit 26 is turned on only when the structure isused-as an air cooling system.

As the air passes through the device 18 into the chamber 16 it is thensubjected to the action of the air conditioning unit which isselectively used either for air cooling or heating purposes. A workingexemplification of this air modifying unit is illustrated in Figure 2 inthe form of an appropriate box-like container 33 of appro== priateproportions and shape, the same having 11% the container is provided asshown in Figure 5 with a coal chute 36 and at a diametrically oppositepoint with a smoke outlet pipe 37 joined to the associated flue 38. Thebottom of the casting forming the container 33 is formed'mto a sort of apan 39 having an appropriately shaped depression 40 which defines atrough. This,

trough communicates with a discharge pipe 41 leading down to the refusebox or pit 42.

The trough and pipe 41 obviously serve to permit ashes to gravitate intothe ash pit when coal is used as a source of heat. When however ice isused a collection pan or suitable receptacle (not shown) is placed inthe pit for periodical emptying.

The gist of the invention is found in the provision of a furnace-likecasing '7 provided with air conditioned outlet 10 to deliver the air byway of ducts 11 to the room registers 12, whether the air be cold orhot, whichever is desired. Secondly, novelty is predicated upon the useof the floor registers 13 and return pipes 14 for delivering the airintothe preconditioning or preparing device 18. As before stated, thisdevice serves to wash the air and moisten the air and when employing acooling or refrigeratingunit 26 serves to additionally cool the air.

After the air is thus pre-treated, it enters the chamber 16 where it issubjected to the action of the modifying and conditioning unit 33,which,

as before stated, may use either ice or coal in orderto acquire thedesired results.

All of the aforesaid features have been carefully selected andmechanically co-ordinated in appropriate order to progressively handlethe air and to provide a single structure which may be employed eitheras a cooling system or a heating system, according to climaticconditions.

menace It is thought from the foregoing description that the advantagesand novel features of the tition in said casing dividing it into upperand lower compartments, means in the upper compartment in alinement withsaid aperture for either heating. or cooling the air passing throughsaid upper compartment, and means in the lower compartment forpre-treating the air before it is allowed to pass into said uppercompartment, said last-named means being in communication with the airintake means and including an inverted conical receptacle carrying a fanhousing, a motor driven fan in said housing, a refrigerating unit insaid housing, a hood-like shield supported on said housing at the upperportion thereof, and a water delivery pipe cooperating with said shield.

2. An air conditioning plant ofthe class described comprising .a casinghaving air intake and discharge means, a centrally apertured partitionin said casing dividing it into upper and lower compartments, means inthe upper compartment in alinement with said aperture for either heatingor cooling the air passing through said upper compartment, and means inthe lower compartment for pre-treating the air before it is allowed topass into said upper compartment, said last named means being incommunication with the air intake means and including a casing havingits top open and-in communication with the upper compartment throughsaid aperture,

a fan housing in the lower part of the last mentioned casing, a motordriven fan in said housing, a hood-like shield supported on said housingat the upper portion thereof, and a liquid delivery pipe for deliveringliquid to said shield.
